Well, unless you're happy that you don't see any image on screen, sure, you can keep yours.
There are used H61 MoBos out there, that you can buy, to replace the one you blew. But the question here is; is only MoBo dead, or are CPU, RAM and GPU dead too? Since those 4 are needed for PC to display the image.
H61 chipset doesn't support CPU OC and the fact that your old MSI MoBo BIOS even has OC Genie is strange. You could've very well shot your CPU.
Here, you need 2nd, compatible PC, to test out each component individually, to see which of them survived and which didn't. Up for testing would be CPU, RAM, MoBo and dedicated GPU (if you have it in your system). Also, what PSU you have? Since poor/old PSU can kill everything it is connected to just as fine as well.
All-in-all, trying to find out which of the component died, is a lot of work and effort, IF you even have 2nd compatible system where to test it all out. Sure, you can go by trial-and-error method, buying new components and replacing old ones, until you get the life back to PC. But CPU-MoBo-RAM = new PC. Also, who is there to tell, that the used components you're buying on 2nd hand market even work? Might as well spend money on 2nd, used MoBo, to find out that it is also busted. Since used hardware is sold "as is" and seller has 0 obligation to return the money, if the bought component is also dead.
Another thing is if you even have the know-how to replace the MoBo. Have you ever took PC apart and/or assembled one on your own? Since MoBo replacement is one tedious thing to do. Not to mention that you have to make a new, clean Win installation as well.
You can go with new hardware just shy of 400 bucks, like so:

CPU has iGPU in it, where you can connect monitor to your MoBo and see the image. CPU cooler is included with CPU. MoBo is micro-ATX, same as your old H61 chipset MoBo. RAM is enough at today's standards (and no, you can not reuse your DDR3 RAM). And to end the package, threw in good quality 650W PSU. Just in case you have dedicated GPU in there, which survived somehow.
The rest of the components your PC has: PC case, SSD/HDD, case fans, you can reuse and don't have to buy new. But you still need to format your C:/ drive and make a clean Win installation.
